"Diego Rivera's famous mural The History of Mexico, showcases the Aztec era to the conquest to the Revolution to the development of industry. It's grandiose and captivating, a unique opportunity to learn about Mexico's past. Not to mention it's free: The mural is housed in a distinguished building east of the Zócalo that operates as a government office. Among the office workers milling about, you'll see a mix of local, national, and international tourists who come to be awe-stricken by Rivera’s masterpiece." - Scarlett Lindeman
